Toxic Effects of Color Photographic Processing Wastes on Biological Systems
1970
LeFebvre, Edward E. | Callahan, Richard A.
The toxicity of Kodak EA-4 processing chemicals as discharged from the Kodak Ektachrome RT Processor was established to Daphina magna (water flea), Pimephales promelas (fathead minnow), and the microorganisms containted in domestic sewage sludge. Untreated and desilvered waste was tested on all organisms. Additionally, the toxicity of the eight individual chemical baths was determined to activated sludge organisms. Activated sludge bench top treatment plants were fed EA-4 waste. The degradation of photowaste achieved by these plants and the toxicity of their effluents to D. magna is reported.
